i am trying to help a friend restoring old cpbackup7.1 floppy disks.
first we copied the program from floppy to hdd (ancient computer with win7 + floppy drives). under dosbox 0.74 it is also executable.
because winimage always crashed right after reading the backups, we finally transferred a 1disk-backup with poweriso as .ima. the image cannot be unpacked by 7z, but is recognized under dosbox as non-standard dos cpbackup.001.
the actual unpacking via cpbackup under dosbox does not work despite mounting the ima as a:. i don't know if this is possible at all, cue: low level?
what possibilities are left to unpack cpb imas - or is this the wrong way?
